Question

16.Sulfur has 16 electrons. After it bonds with Magnesium it acquires a 2- charge. How many electrons does the S2- ion contain?Select one:a. 2b. 8c. 16d. 18

Answer 1

18 electrons.

Explanations:

According to the question, we have that sulphur has 16 electrons and after bonding with magnesium acquired a 2-charge. The sulphur ion S2- shows that sulphur has gained 2electrons to become stable.

Amount of electron S2- have = 16 electron + 2electrons

Amount of electron S2- have = 18 electrons

Hence the number of electrons S2- ion have is 18 electrons.
